This invention relates t 'o scum' gutters, and has more partiularreference to astruc-i ture especially applicable to` swimming pools' and the like, although .it is capable Vof use generally where vit` sought to rem-ove, by surface drainage, from a liquid, foam, scum, andi otlgienlloat'ing material. ACertain 4fea'-i tures` of the invention', also, are capable of wide application to gutters generally.

'An object ofl t'hje'- invention is" t`o provide an improved' form of gutter which may be simply constructed in transverse section` of only two sectirrns or' blocks. y

VAnother object i's to' provide` an" improved corner structure" adapted` to` compensate for expansion inthe walls of the pool.

furtl'lerobject isthe provision of an improved manner of connectingthedrain to the gutterso' that constructionof the pool is ezq'geditedy its use. l' I Gther obects of the invent-ion', some of which aremore or less incidental or ancillary tothe foregoing, will appear in the course ofthe following description. y r

The said blocks; halve'vflat bott-oms l, and flat rea-r and front faces; 5 and 6; respectively. A preferably yconcavebottomed gutter 7 is formed' in theV blocks 1 intermedia-ry of :the upwardly" projecting n frci'itx and rear lanfgesfand- 9, respectively. The flanges-8 haye rounded tops" 10;, and's the flanges 9 haw/*e flat tops" ll disposed on a higher'level than thet-o'ps 10i A course' of corbelv bloclzs l2 is laid on'V the @curse or' gutrer broers r', the Het Bottom face ofl the' corbelv blocks meeting thetop face 11 ofthe gjutter'blbcks 11, and the' front face: 14' of `the corbel blocks being forwardly andE upwardlyficlinedi, being preferably coltcave at its lower portionlto forin'al continu'- ous` and unbroken surf-acev with the'V rear gutter facel of thegutter blocks 1:, and con'- veX' atitfs" upper portion' so' that `they upper portion'-terminates; as a verticalicontinuation ofthefro'nt faces 1'6' of the'blocks superpose'd on the .corbelf bloclis' 12. T he' face's" 1'6: are preferably' disposed ink retracted relation'ft'o the faces' 6, so thati thelange 8`is made' more readily accessible asia life rail, and so that water' lfronti' theV curb 17 does not flow back into" the pool, but drains intfo the' gutter 7. The' rearend 18 ofthe corbell blocks projects beyond the rear` face 5' of the; gutter blocks 1il inforderto balance the weight of the front portion overhangin'g the gutter' blocks. y

TheA curb 17 is preferably formedof suit'- able non-skid materia- 1, such as roughened .tile and'tlie lik'e`,-a'nd may' be disposed' at: any suitable height' above the gutter 1l by the interposition of appropriate br'ickwork` and the like between the Curbj17 and the'ecrbel blocks 12.A In the present instance, the bricl'work consists' o'f a lower course of fiatters 19, an intermediate courseY of headers and stretchers 20, 'and au upper course ot flatters 531 which may bear suitable distance markers.

The blocks l are laid so that the bottoni of the `gutter 7 and the top lll ot the lite rail or flange 8 are level, and drain pipes are vonnected to thc gutter at suitable intervals, ereferably ot about ten feet. For this purpose, some of the blocks l) are termed with a central cylindrical opening :Ell extending through their bottoni walls or webs ifl, the said openings enlarging laterally all around at their upper and lower ends to forni retracted shoulders and 1lb, respectively, best shown in Figure 7. il sleeve 27 lits in the opening 23 and is internally screwthreaded to fit an exteriorly scrcW-tlireiuled inner sleeve 2S, the inner sleeve 2S having a flange 2S) which bears on the upper shoulder :'25 and the outer sleeve having a. flange 30 which bears on the lower shoulder 2G. The 1piping preferably lead, passes through tie inner sleeve and flares outwardly at its upper end to forni a tlange 3l that is clamped between the flange 29 and a ring 32 secured to the flange 29 preferably by means of' suitable screws. A drain sieve 33, preferably of the inverted cup or bee hive type, tits Within the ring Instead of the beehive form oit drain shown in Figures l, 2, and 7, a form of d ain shown in Figures 8, 9, and l0 may be used. The said drain comprises a substantially pyiainidal receptacle or box 34., having a grate 35 secured to the open top thereof in any suitable manner and so that it preterably lies flush with the bottoln of the gutter 7. The lower end of the box develops into an annular neel; 3G, externally threaded to receive a flanged clamping ring 37, cooperating with flanged pipe section 3S to secure the said pipe thereto. Pipe section 38 is secured to elbow pipe sect-ion 39 through union el() threading thereon. Pipe 38 is first roughly located in place and the concrete portion of the Wall poured around the same. Pipe section 38 is preferably of lead so that it may be easily manipulated to nally locate the box 34 more exactly in its appropriate position, the vertical adjustments being effected by changing thelcngth of the pipe 3S and, also, by using packing Ll1 of suitable thickness in the unions 37 and 40. Special gutter blocks 42 are formed with re` cesses l-l in one end to accommodate the drain boxes 3l. The recesses preferably enlarge late 'allliv at their upper ends to forni depressed seating faces la for the flanged upper end of the boxes. The blocks 4:2 are formed right and left, and are placed together end to end so as to inclose the box 3st after the latter has been fixed in place. The other blocks 1 of the gutter are then laid in the course.

It will be observed in Figure 2 that the corner gutter blocks 45 are formed right and lett and are joined at end faces Llli arranged convergingly toward the internal corner ot' the meeting walls with respect to the transverse other end faces -l`7 of thesaid blocks l5, preferably at an angle of forty-five degrees thereto. rl`he end laces l-S of the corbel blocks 12 are staggered with relation to the end 'faces f7 ot' the gutter blocks l, as best shown in Figure Those blocks l2 nearest the corner have oblique end faces 4:9 adapted to fit the converging end faces of a special corner block 5l interposed therebetween. The faces ell) and 50 are in staggered relation with respect to the :faces 46 and 47 of the glitter blocks. rllhis arrangement of oblique faces enables the blocks to shift slightly with relation to one another parallel to the said oblique faces, and so compensate for any undue or unequal expansion of the Walls resulting from changes in temperature or other causes.

Figure 4t illustrates special corbel blocks 52 and gutter blocks 53 for forming the external corners 54 of walls having recesses 55 therein. Figures 5 and G depict other forms of external corner blocks for recesses of different depths.

lhe gutter and corbel blocks may be formed of any suitable material, but plastic clay is preferable. The blocks and the brick lin ing ofi the poel are preferably enameled on their exposed faces.

Having thus fully described this invention, I hereby reserve the benefit of all changesl in form, arrangement, order, or use of? parts, as it is evident that many minor changes may be made therein Without departing from the spirit of this invention or the scope of the following claims.

l claim:

l. In a structure of the class described, the combination of a block having front and rear upwardly projecting fianges to form an intermediate gutter; and a second block having its bottoni face supported on the top face of the rear flange, and having a front portion overhanging the said gutter and forming a. continuation of the rear 'face of said l`gutter, the rear portion thereof project ing beyond the rear face ot' the flanged block to balance the Weight of the overhanglng front portion.

Q. In a structure of the class described, the combination of a block having a groove defined by flanges. and a second block having its tront face forming a continuation ot said groove and having its rear portion pro jecting beyond the rear face ot' the inner flange of said first-na1ned block.-

In a structure of the class described, the combination of a block presenting upwardly directed flanges to forni a gutter and a second block disposed on the rear flange of the first-named block, the front face there- Til of forming a continuation, said gutter and the rear portion of said second-named block projecting beyond the rear face o said rear ange. i

4. In a structure of the'class described, the combination of a block presenting upwardly directed flanges to forni a gutter, and a Second block disposed on the rear iange of the tiret-named block, the front face thereof forming a continuation of said gutter and 10 terminating inwardly of the front face of the inner flange of said irst-nanied block, the rear portion of the second-named block projecting beyond therear face or' the rear ilange of said irst-narned block.l

In testimony whereof I hereunto affix rny slgnature.
